My abiding memory of the Royal Marines comes from a few years back, when our rifle club used to hire the local military rifle range here in Somerset. There's a Marines camp about 10 miles down the road from the range.
We'd booked the range about 3 months in advance and turned up to shoot. Just as we were about to get down on the firing point, a helicopter roared in overhead and swayed to a halt, just missing sticking its tail rotor in a large oak tree...
It was the Marines; they'd got their dates mixed up. True, it was our day for the range, but what the hell, they had priority; so we packed up our gear and got ready to leave. At this point it transpired that the Marines had arrived with their 5.56mm rifles, and several thousand rounds of 9mm ammo...
This proved to be more than the officer i/c could handle. He told us we could have the range for the day - for free, because of the inconvenience - loaded his men back into the chopper, and roared away into the clear blue sky; this time missing the oak tree by a whole 6 feet.
We were proud of ourselves. We managed to wait till they were out of sight before bursting into fits of helpless laughter.
I guess we all have our off days.
Seriously, the Marines are great guys; tough as nails, professional, well trained and superbly led. God speed.
